You do need to use () for that macro, btw.

As far as keys not to pass, that's personal preference depends how you set up. For me, I don't pass num lock, and I don't pass number keys 1-6 or WASD. I pass everything else.

Reason being is I control 3 sets of controls with 1 keyboard. The warrior gets 1-6, priest gets 7-= and the dps get Y-]. Puts all my controls at my finger tips for fast reaction times. Num lock is obvious, I don't want everyone to autorun, just the main. And wasd so they don't move and break follow unless I use the arrow keys.
